Abstract
A word processor having attribute functions such as underline, boldface, superscript, etc., can produce or cancel those attribute effects on the display device by simple operations. The word processor with an attribute mode can either produce the attribute effect which is selected by an attribute key in response to the rightward or downward movement of the cursor, or cancel it in response to the leftward or upward movement. The word processor with an attribute cancel mode in addition to an attribute mode can set a mode among a non-attribute mode, an attribute mode and an attribute cancel mode independent of the direction of the cursor's movement.
